Alphabet Inc (NASDAQ:GOOG) (NASDAQ:GOOGL) spent most of the past two years in the market's penalty box. Today, it's the comeback kid propelling hedge fund P&Ls into the stratosphere. When news broke Friday night that Warren Buffett's Berkshire Hathaway Inc (NYSE:BRK) (NYSE:BRK) had taken a $4.3 billion position in Alphabet, the stock jumped 3% on Monday — but the real winners were the managers who were already sitting on Google long before Buffett walked in.

Berkshire's 17.85 million new shares at roughly $209.67 may age well, but Buffett missed the most explosive stretch.
Alphabet is now up 50% year to date, outperforming every megacap peer as investors finally acknowledge Google's AI readiness — from TPU momentum to Cloud reacceleration to the impending Gemini 3 reveal.
